NUTRITIONAL STATUS AND URINARY IODINE LEVELS OF SCHOOL-AGED CHILDREN: IS THERE A CORRELATION?

Öz

Objective: Impaired physical growth is one of the prolonged effects of deficient iodine, a micronutrient. Thus, this study aimed to determine the relationship between the urinary iodine levels and anthropometric indices in a population of schoolchildren in Ilorin, North-Central Nigeria. Material and Method: This was a cross-sectional analytical study carried out among primary schoolchildren in Ilorin, North-Central Nigeria. We recruited a total of 492 children aged 6-12 years through a multi-staged systematic sampling technique. Anthropometry was determined using standard methods. We collected urine samples from the pupils and analysed them for iodine in the laboratory using the Sandell-Kolthoff method. Results: Of the 492 children recruited, 13 (3.2%) were under weight, 23 (4.7%) were stunted, 21 (4.3%) had thinness and obesity was found in 7 (1.5%). The mean (SD) weight for age Z score (WAZ) was -0.216 (1.089), and height for age Z score (HAZ) was -0.073 (1.286). The mean weight for height z score (WHZ) and weight for age Z score (BAZ) were 1.036 (0.002) and -0.428 (0.976) respectively. A total of 26.5% of the schoolchildren had mild iodine deficiency, 0.4% had excess urinary iodine levels and no child had moderate or severe iodine deficiency. There was no relationship between the urinary iodine levels and anthropometric indices (WAZ p=0.665, HAZ p= 0.978, WHZ p=0.375, and BAZ p=0.928). Conclusion: This study showed that there is no relationship between nutritional indices and urinary iodine levels. Hence, nutritional status of schoolchildren may not reflect their iodine level.

Amaç: Bozulmuş fiziksel büyüme, bir mikrobesin olan iyotun eksikliğinin uzun süreli etkilerinden biridir. Bu çalışma, Kuzey-Orta Nijerya'daki Ilorin okulundaki bir popülasyonda idrarda iyot düzeyleri ile antropometrik endeksler arasındaki ilişkiyi belirlemeyi amaçlamıştır. Gereç ve Yöntem: Bu çalışma, Nijerya'nın Kuzey-Orta Ilorin kentindeki ilkokul çocukları arasında yapılan kesitsel bir analitik çalışmadır. Bu çalışmaya, çok aşamalı sistematik örnekleme tekniği ile 6-12 yaş arası toplam 492 çocuk dahil edildi. Antropometri standart yöntemler kullanılarak belirlendi. Öğrencilerden idrar numuneleri toplandı ve Sandell-Kolthoff yöntemi kullanılarak laboratuarda iyot açısından analiz edildi. Bulgular: Çalışmaya katılan 492 çocuğun 13'ü (%3,2) yaşına göre kilosunun altında, 23'ü (%4,7) kısa boylu, 21'inde (%4,3) zayıflık vardı ve 7'de (%1,5) ise obezite saptandı. Yaş Z skoru (WAZ) için ortalama (SD) ağırlık -0,216 (1,089) ve yaş Z skoru (HAZ) için yükseklik -0,073 (1,286) idi. Boy z skoru (WHZ) ve yaş Z skoru (BAZ) için ortalama ağırlık sırasıyla 1,036 (0,002) ve -0,428 (0,976) idi. Okul çocuklarının toplam %26,5'inde hafif iyot eksikliği, %0,4'ünde aşırı idrar iyot düzeyi saptanırken çocukların hiçbirinde orta veya şiddetli iyot eksikliği yoktu. Üriner iyot düzeyleri ile antropometrik indeksler arasında ilişki yoktu (WAZ p=0,665, HAZ p=0,978, WHZ p=0,375 ve BAZ p=0,928). Sonuç: Bu çalışma beslenme indeksleri ile idrarda iyot düzeyleri anthropometarasında bir ilişki olmadığını göstermiştir. Bu nedenle, okul çocuklarının beslenme durumu iyot seviyelerinin bir yansıması olmayabilir.
